To aZZ whom it may conoerm;

Be it known that I, FRANCIS W. ROBINSON,

of Richmond, Wayne county, Indiana, have invented certain new and useful Improvements in Thrashing-Machines and Stacker Attachments ,Therefor, of which the following is a specification.

This invention pertains to improvements in thatclass of thrashers having, incorporated In this with them, air blast tube stackers. class of thrashers, the thrasher itself has been provided with a tail chamber to receive the straw, the stacker tube rising from this chamnent tailward extension of the general thrashing structure. The principle of construction was'such that the stacker required tobe contemplatedin the fundamental thrasher, and, e

if it was desired that a stacker should be provided for while not at once applied, a very material modification and increased expense was involved in the thrasher. Under that system it would be impossible vto make the thrasher without the stacker but provided to receive it, without adding very much to the expense of the thrasher. The rear wheels of the thrasher were located below the tail-chamher which pertained to the stacker; but airblast .tube stackers have been arranged upon a system different from the compound or incorporated system above referred to. The stacker tube, with its base chamber to re ceive the straw, has been constructed as a complete independent machine and mounted .on wheels so that it could be transported by means of a team. When this stacker was to be used, it was to be wheeled up to the tail of the thrasher so that the thrasher might tail its straw into the receiving chamber of the stacker. The only connection between the thrasher and the stacker consisted of a belt from which one of the thrasher shafts gave motion to the stacker mechanism. Such arrangement of stacker and thrasher did not goform a combined machine, but formed simply two associated or aggregated machines, brought into convenient position with reference to each other for use at the same time; and when the machines were being transported there was no community of interest whatever between them. The disadvantages of these separate machines are obvious, and are such as to have rendered them impracticable, and the universal custom has been to embody the principle of combination as first above referred to, that is to say, such a special construction of the thrasher that it would form a part of the stacker.

In either of the two types above referred to, the wheels were placed under the stacker chamber, such wheels being either the rear wheels of the thrasherin the one case, or, in the other case, the special wheels of the separate stacker.

By my improved construction, thethrasher, fitted to receive the stacker at any time in the future, calls .for no increased expense or complication in the structure. The stacker, when provided in the future, can be readily attached to the thrasher by common laborers,

and the construction of parts incidentto the stacker is much simpler and much less expensive than usual.

In my construction the rear wheels of the thrasher are placed entirely forward of the plane of the juncture between the thrasher and stacker and still these Wheels become the wheels of the stacker when a stacker is provided. The thrasher is entirely complete without the stacker, which is merely an attachment that can be applied to and removed from the thrasher at will; but when the stacker at any time is added, it becomes to all intents and purposes one structure with the thrasher for the time being, attached thereto, and utilizing the thrasher frame and thrasher wheels and thrasher team as the means forits transportationand this I believe to be broadly new with me.

When the combined structure is being transported the stacker tube is turned forwardly over and in line with the thrasher so that the additional weight due to it is fairly balanced upon the rear wheels of the thrasher.

My improvements will be readily undertoo stood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of the rear portion of a thrasher provided with a stacker, of the class in question, and illustrating my invention. Fig. 2 is a similar view of the rear portion of the thrasher with the stacker removed. Fig. 3 is a similar view of the stacker portion removed from the thrasher; and Fig. 4 is a vertical longitudinal section of the tail chamber, separated from the thrasher and from the stacker tube.

In the drawings:-1 indicates the body portion of an ordinary thrasher and separator; 2, the rear wheels thereof, with their axle near the extreme rear of the thrasher-frame; 3, vertical end frames of the thrasher at the extreme rear of the thrasher; 4, the usual stacker tube; 5, the usual swiveling base of the stacker tube; 6, a base chamber on which the swiveling base of the stacker tube is mounted; 7, the stacker fan, disposed in the base of this chamber; 8, vertical frame timbers at the front of chamber structure 6 and adapted to set with their front faces against the rear faces of the frame timbers 3 of the thrasher, the lower ends of timbers 8 resting upon rearward projections of the sills of the thrasher; 9, bolts clamping the upper portions of timbers 8 and 3 firmly together; 10, bolts clamping the lower portions of those timbers together; 11, the main sills of the thrasher, projecting rearwardly beyond timbers 8 sufficiently to receive the bases of timbers 8; 12, the top seat of chamber 6 to receive the swiv-- cling base 5 of the stacker tube; 13, carrier within the chamber 6 to receive the straw from the thrasher and carry it rearward under the base of the stacker tube within the influence of the stacker fan; and 14:, cast brackets secured to the framing of chamber 6 and of the thrasher to receive the bolts 9.

thrashers, and by inspecting Fig. 3 it Willbe' seen that the tail chamber construction for the thrasher is of peculiarly simple and effi- 5o cient construction.

It will be obvious that thrasher framing constructed as in Fig. 2 adds no expense whatever to the thrasher on account of its adaptation to receive a stacker in the future. The stacker is applied to the thrasher by setting chamber construction 6 against the rear of the thrasher, with timbers 8 against timbers 3 and resting on the thrasher sills, after which bolts 9 and 10 are applied, completing the structure.

The chamber structure is supported wholly by the thrasher body and its wheels, the latter providing the support for the combined structure. The stacker tube may be turned into horizontal line forwardly over the thrasher so as to fairly balance its weight upon the rear wheels of the thrasher When the combined structure is being moved from place to place.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The combination, substantially as set forth, of a thrasher-body having vertical frame timbers at its rear, a rear wheel axle under said body near said vertical frame timbers, a chamber structure provided with front frame timbers, a stacker-tube mounted upon said cham ber structure, and clamps uniting the frame timbers of said chamber -structure to the frame timbers of said thrasher-body.
